Tennis star Roger Federer is in excellent form this summer in London. The 35-year-old gave yet another display of almost perfect tennis on Friday to edge closer to his eight Wimbledon, and 19th Grand Slam title. He defeated Germany's Tomas Berdych 7-6 (4), 7-6 (4), 6-4 in 2 hours, 18 minutes.

Earlier, in the first volatile semifinal clash, Marin Cilic emerged winner after 2 hours and 56 minutes of action. The 28-year-old, the world No. 6, over came the gentle American Sam Querrey 6-7 (6-8), 6-4, 7-6 (7-3), 7-5 to make his way into the Wimbledon final for the first time.

Cilic, who had a poor start to the season going out in the second round of the Australian Open, rediscovered his form in Istanbul in May, where he clinched his first title of the year.

Thereafter, with Swede Jonas Bjork man in his corner, the Croat has managed a steady climb, so much so that before the start of Wimbledon, Federer had predicted that the youngest of the four men in the last four could go deep in the draw.

'Unbelievable' was how Cilic described his crackling play on the day.

He had 25 aces and 70 winners, taking his tournament count to 130 (aces), but it was not just the serves, whatever the weight of the delivery.

Cilic backed his serve with some daring shot making; he had 26 fore hand winners, service returns where he cut Querrey's angles and crunched shots that whistled through the air.

"I'm playing well, more so as the tournament has unfolded. This was a hard-fought battle, especially the first set," Cilic said of the semifinal.

Querrey, who came through three successive five-setters to make the semifinals, was all praise for his opponent, who he now hasn't beaten in five meetings.

"He's tough on both sides. I kind of felt like he pushed me around a little bit today," the 29-year-old said. "I had that break in the fourth set. When he broke me back, he played a great game. That kind of deflated me a little bit. He does everything really well. He didn't seem to have many holes (in his game). I played him a handful of times before, lost a bunch. But he did seem to play at a really high level today."
